Apple iPhone 4 16GB Used

The iPhone 4 is now boxier, with the rear side now flat, instead of rounded. It will keep the 3.5-inch display diagonal, but will quadruple the pixels to 640x960, making it the highest-resolution screen on a smartphone to date. The other new stuff includes a front-facing video call camera, 5MP main camera lens with LED flash and 720p HD video recording, Micro-SIM slot, instead of ordinary SIM, a secondary mic for noise-cancellation and a lot of other new features.

Features for Apple iPhone 4 16GB Used

iPhone 4. In so many ways, it`s a ﬁrst.

While everyone else was busy trying to keep up with iPhone, we were busy
creating amazing new features that make iPhone more powerful, easier to use, and
more indispensable than ever. The result is iPhone 4. The biggest thing to
happen to iPhone since iPhone.

Face Time

People have been dreaming about video calling for decades. iPhone 4
makes it a reality. With just a tap, you can wave hello to your kids, share
a smile from across the globe, or watch your best friend laugh at your
stories iPhone 4 to
iPhone 4 over Wi Fi. And it works right out of the box. No other phone makes
staying in touch this much fun.

Two Cameras Two Views

iPhone 4 has two cameras: One on the front, which focuses on you. And one on the
back, which focuses on everything else. FaceTime lets you switch back and forth
between them at any time during a video call. All you have to do is tap a
button.

Retina Display

The Retina display on iPhone 4 is the sharpest, most vibrant, highest resolution
phone screen ever, with four times the pixel count of previous iPhone models. In
fact, the pixel density is so high that the human eye is unable to distinguish
individual pixels. Which makes text amazingly crisp and images stunningly sharp.

Multitasking

iPhone 4 introduces a whole new way of multitasking. Now you can run your
favorite third party apps and switch between them instantly without slowing
down the performance of the foreground app or draining the battery
unnecessarily.1 This smarter approach to multitasking is available only on
iPhone.

HD Video Recording and Editing

Shoot your own movies in high definition. Capture impressive video even in
low light settings, thanks to the advanced backside illumination sensor and
built in LED light. Then edit and create your own mini masterpiece right on iPhone 4 using the new iMovie app with Apple designed themes, titles, and
transitions.

5 Megapixel Camera with LED Flash

Take beautiful, detailed photos with the new 5 megapixel camera with built in
LED flash. The advanced backside illumination sensor captures great pictures
even in low light. And the new front facing camera makes it easy to take
self portraits.
